Application filed July 5, 1924. Serial No. 724,327.

To all whom it may concern:

Be it known that I, ALBERT H. 'TINNER- MAN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in an Oven-Door Hinge, of which the .following is a full, clear, and exact description, reference being had to the accompanying draw mgs. I

This invention is directed to improvements in door hinge constructions and particularly to hinge constructions for stove oven doors.

The general object of my invention is directed to the provision of a hinge construction for a door or compartment closure means which may be completely concealed when the door is closed. A further object of my invention is the provision of a hinge construction for an oven door which is adaptable for supporting the door in an open position without causing the door to close and which will react on the door when the door is swung from a full open position to close it and maintain it closed.

A further object of my invention is the provision of a hinge construction for pivotally supporting the door upon a sh ftable axis whereby the hinge construction may be drawn into the oven closure and thereby permit the marginal edges of the hinge construction showing the relationship.

of the parts when the door is in a full open position; Fig. 3 is a cross-sectional plan view of the hinge construction illustrating the parts with the door in a full open position; Fig. 4 is a perspective view of the front of an oven structure illustrating the neatncss in the "appearance of a stove oven vance of the front of the stove.

to the accompanyingv structure which is obtained when provided with my novel hinge construction.

It has been the practice to provide an oven door with a heavy hinge construction usually comprising separable hinge castings bolted or otherwise secured on the outside of the front frame ofpthe oven whereby the door, when opened, may be used as distance below the bottom edge of the door supposedly eliminated this closing or seali-ng deficiency, but this required 'a heavier hinge construction due to the additional overhang of the door when completely open. This arrangement also resulted in a gap between the door frame and' front frame when the door was open. Likewise the incorporation of a spring or some resilient means to cause the door to close when swung from its normally open position, greatly increased the bulk of the hinge construction which detracted from the general appear- My invention contemplates a hinge construction which is comparatively light and can be completely concealed when the door is closed and will permit the door to properly seat on the front frame completeiy around the marginal edges thereof.

I: show in the drawings an oven structure for a gas stove comprising an oven structure having a partitioning member P dividing the interior of the structure into a baking oven com artment A and a broiler oven compartment The burner K is disposed directl beneath the partition memer P. Eac oven compartment is provided with a door suspended upon my novel hinge construction as will be presently described. i

A preferred form of my invention comprises two bars 10 extending from the rear to the front of the stove through the oven compartment adjacent the bottom 'wall thereof. If desired these bars may extend through the door opening or if desired could be concealed by the lining of the oven and extend through suitable openings formed in the front frame. The embodiment disclosed is of such a simple character that it may be incorporated in the stove, as shown in Fig. 1, in such manner as to be completely concealed by the doors when the doors are closed. I therefore provide hinge lugs 11 adjacent the inner edges of the door frames 12, which may extend upwardly through openings formed in the door linings 13 and these lugs may be secured to the outer ends of the bars 10 by any suitable means such as bolts 14,

I prefer to have the rear ends of the bars 10 rounded and adapted to extend through suitable openings formed in the outer back panel 15, and inner lining panel 16, of the rear Wall of the oven and I accordingly reinforce the outer panel 15 with transverse straps 17 through which the ends 10 of the bars 10 extend. On the rear ends of the "bars 10- are spring members 20 held in place amount of compression imparted to the springs by adjusting the nuts 21.

i As shown in Fig. 2 relation of the front ends of the bars to the lugs 11 is such that the bottom edge 25 of the door frame 12 may abut the lower, or underside of the bars 10 whereby this edge reacts upon the bars to maintain the door in a normally horizontal position as shown in Figs. 1 and 2 and the bars carry the weight of the door in the position shown by resting u )On the edge 26 of the door opening former in the front frame 26. If desired, side lugs 27 may be provided, extending from the side margins of the front frame door openings to guide the bars 10'along a horizontal path. Such lugs, however, are not essential to the proper functioning of the hinge construction shown.

It will be seen that this simple hinge construction has many advantages over the old form of hinge construction in that when the door is swung to a closing position, there is no fixed pivotal center for the door and the door accordin l can come to a ro er seating or scaling relation to the frame 26 around the four edges thereof. Furthermore, when the door is in the open position as shown, the bars 10 serve to maintain the edge 25 of the door against the front frame, thus presenting substantially a continuous surface comprising the oven door lining 13. the door frame edge 25, and the edge 26 of the front frame, thus greatly facilitating the sliding of utensils into the oven. It will be seen also, that the hinge construction is completely concealed by the door, as shown in Figs. 1 and 4, when the door is being closed and the spring members, disposed at the rear of the stove, function through the bars to maintain the bars with the edges thereof in proper seated relation to the front frame, while imparting to the bars a uniformity of action which permits a ready and easy swinging of the door when either opening or closing. When the door is completely open the relationship of the lugs 11 and the bars 10 and the reactions thereof upon the front frame 26 is such that the springs do not have any tendency to cause the doors to close in an unexpected manner. In other words, the present hinge construction has the advantage of the usual spring hinge in that the springs have a tendency to overcome the weight of the door when closing the same, but when the door is in an open position it need not be held.

The spring member as, shown may be disposed at the rear of the stove remote from the depreciating influence of the heat of the oven and may act through the bars to cause the door to seek a proper seat on the oven frame regardless of any slight imperfections or irregularities in the seating edges of the door frame.

It should be understood that while I have illustrated my novel hinge construction as adapted to the supporting of an oven door for a stove, it, nevertheless, is adaptable to a variety of closure means for compartments such as filing cabinets, lockers, etc.

I claim:

1. A compartment closure means comprising a door, shiftable door supporting means extending through an opening of the compartment including a pivotal connection be tween the door and said means which is shifted through said opening and resilient means for shifting the door supporting means when the door is swung to a compartment closing position.
